In my message of April 8 I wrote one point about MathML performance issues
with one popular browser.
In reply to David Carlisle i added more information in my message of day
April 14.
I have been discussing about this off-list and it has been confirmed by
Luca Padovani that an example file takes him about 7 minutes to load it in
Firefox 2. Boris Zbarsky confirms that it takes a long time to load in
Firefox 2 in his machine [1].
Boris has also confirmed [1] the same file takes about 5 seconds to load
in the last Firefox 3 beta. Since users will update to next FF 3.0 before
HTML5 was ready, the current performance issues may be not taken into
account by the HTML5 group.
